Nemifitide diTFA (INN 00835 diTFA) is a synthetic pentapeptide antidepressant with a potential for rapid onset of action. Nemifitide diTFA is a peptide analog of melanocyte-inhibiting factor (MIF)[2]. Nemifitide diTFA can cross the blood-brain barrier.In Vitro: Nemifitide diTFA (INN 00835 diTFA) and its active metabolite (M1) bind at micromolar concentrations to several receptors including the 5-HT2A, 5-HT2C, melanocortin MC4, MC5 and bombesin.In Vivo: Nemifitide diTFA (INN 00835 diTFA; 0.3 mg/kg; IP; daily; for 14 days) significantly increases swimming in the FSL rats after just 5 days of treatment and has long-lasting effect[2].
Nemifitide diTFA (0.0125-15.0 mg/kg) significantly increases swimming in the FSL rats at both low (0.025-0.3 mg/kg) and high (3.0-15.0 mg/kg) doses but not at intermediate (0.4-2.4 mg/kg) doses[2].
